Pranks and uncomfortable situations; What are your stories?

After overseas deployment,I had @5 months left in service.When checking in at Ft.Hood,the Company Commander informed me that the soldiers were in the field and would be for 3 days.I was told to go through the barracks and inform every one I see,to get a haircut.It didn`t take long to figure the CC was probably rolling on the floor laughing.Everyone left was a returning Vietnam veteran with less than 72 hours left in the Army.Needless to say ,I didn`t receive many hugs that day.
